HOSE CONNECTION.

To all who-1n it may concern Be it known that I, RICHARD DE KUYPER, Jr,a citizen of the United States, residing at Hooper, in the county ofWeber, State of Utah, have invented certain new and useful Improvementsin Hose Connections; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to hose couplings, and it more particularlyrelates to an improved form of hose coupling which is especially adaptedfor air brake connections.

An object of the invention is to provide a hose coupling of thischaracter in which the oppositely disposed elements are interchangeable.

Another object is to provide a hose coupling of this character which isof simple construction, easy to operate, strong, comparativelyinexpensive, and thoroughly efficient.

Other objects and advantages may be recited hereinafter and in theclaims.

In the accompanying drawings, which supplement this specification:Figure 1 is a longitudinal vertical sectional view through my improvedhose coupling complete. Fig. 2 is a top plan view of the complete hosecoupling. Fig. 3 is an end elevation of one of the outer couplingmembers, the inner coupling member being in section, and Fig. 4: is aperspective view of the complete inner coupling member.

Referring to these drawings, in which similar reference characterscorrespond with similar parts, throughout the several views: Thecoupling consists of two counterpart outer members 5 and an innercylindrical member 6 having counterpart and interchangeable endportions. Each outer cou pling member consists of a shank 7 on which thehose is to be seated, and an enlarged end portion 8 provided with acylindrical bore 9 and a rectangular recess or channel 10 communicatingwith each other. The periphery of each element 5 is provided with aradial bore or recess 11, communicating with the recess 10, forreceiving a pin or fastener member 12. This fastener member is adaptedto fit snugly in the recess 11 and to extend to the point at which therecess 10 merges with the central bore or recess 9. Each element 5 isalso provided with an eye Specification of Letters Patent.

or apertured lug 13 to which a chain 14 may be attached for connectingthe pin 12 thereto. Each outer section of the coupling is provided witha cylindrical tubular element 69 15 which extends into the centralrecess 9, being concentric therewith, so as to provide an annular space16. The bushing or tubular member 15 extends through the shank 7 and issnugly fitted therein, and extends to the medial portion of the recess9.

The member 6 is of substantially cylindricalshape, and either end may befitted snugly within either of the members 5, while the bushing 15 ofeither member 5 fits snugly within the contiguous end of the member 6.This member 6 is provided with a longitudinal rib 17 which is notched at18, for the reception of the pins 12, this rib being fitted snuglywithin the opposing and alined recesses 10 of the outer couplingsections. One or more Washers 19 of rubber, leather or other suitablematerial are fitted snugly within each annular recess 16, so as toeffectually prevent any possible leakage be- 30 tween the end wall ofsaid recess and the end wall of the member 6.

From the foregoing, it will be seen that the member 6 may be reversedwith relation to either or both of the members 5, without 35 altering oraffecting the function or operation thereof, and it will also be seenthat when this hose coupling is used in a train line, for air brakes,etc., the pin 12 may be removed from either member 5 so as to leavethemembers 6 in engagement with the other outer coupling member, whenuncoupling the hose. However, when it is desired to couple one of thehose connections or sections with another similar section, in the eventthat one of the members 6 is already in engagement with each of themembers 5, then, either of the similar members 6 may be removed andplaced in safe keeping for future use, so that the remaining member 6may be quickly engaged with both outer coupling members, for unitingthem in the manner illustrated.

It will be seen that I have provided a hose coupling of this characterwhich is fully capable of attaining the foregoing objects, in athoroughly practical and efficient manner.

I do not limit my invention to the exact details of construction,combination and arrangement of parts, as herewith illustrated anddescribed, but my invention may only be limited by a reasonableinterpretation of the claims.

I claim:

1. A hose coupling consisting of two counterpart and interchangeableouter sections each of which is provided with a cylindrical bore and arectangular channel merging therewith and a radial bore communicatingwith the channel, a tubular member extending into each of said cylindrical bores and providing an annular reeess in each bore, and areversible inner coupling member having counterpart end portions whichfit within said outer sections and being provided with a notched ribwhich fits snugly in said channels while its ends are seated in saidannular recesses, and fastening means fitted within the radial bores andextending into the notches of said 2. A hose coupling consisting of apair of counterpart and interchangeable outer sections each comprising ashank and an enlarged centrally bored end portion and having a radialbore communicating with the central bore, a cylindrical ,bushing fittedsnugly in each of the shanks and extending into the central bore to apoint between said radial bore and the inner end of said central bore, acylindrical member having counterpart end portions fitted snugly aroundthe bushings and fitted snugly within the central bores, and fasteningmeans extending through the radial bores and engaged with saidcylindrical member.

3. A hose coupling including mating outer members having registeringlongitudinal inner slots or grooves, an inner coupling member having alongitudinal rib snugly fitting in said grooves, said rib being providedwith central notches, and pintles carried on flexible attaching means onsaid outer members and engageable in the notches formed in said rib.

In testimony whereof, I afi'ix my signature, in the presence of twowitnesses.
